We originally had issues with our HVAC (AC) not cooling properly for the first and second levels of…read moreour home. In the past we had another HVAC service firm whom we parted ways with due to unsound business practices (they suggested replacement of $5,000 AC units even though they only had a small leak. The other firm also replaced parts that could have been fixed and there was a pattern of constant upsell and overcharging (we verified this with independent professionals). This led us to Cork's here in Huntley, and it was a great decision. Cork's sent someone very quickly, even though there were many other customers with similar issues this time of year. Gil did the original inspection and then Frank (owner) came a day later as we had to wait for the coils to defrost completely, which made sense. Both were very knowledgeable and trustworthy. They did not give me a bunch of BS about replacing the entire unit, but rather refilled the Puron and injected a dye/sealant. We will monitor it over the next year and call them if we notice issues. They suggested that these 2008 units should have a decent lifespan (possibly up to 20 years if built well) and that most repairs can be done part-wise as things are properly diagnosed over time and replaced. This built a lot of trust with me out of the gate. All of Frank's employees work directly for him, not on commissions, and you don't get the sense there's a constant 'upsell' or 'vague rationale' for larger more costly replacements. The other very great experience was this. We had two toilets that for over year now have been refilling their water tanks on their own constantly (and increasing water $). I replaced the intakes and flappers myself twice to no avail. Frank took the time to fix both toilets in a matter of minutes and knew exactly what the problem was, right during the service for the HVAC. It was nice of him to make the time as I know he was already in hurry to his next appointment but wanted to make sure I was a satisfied customer. We appreciate Cork's business ethics, professionalism and willingness to go above and beyond for customers. Thank you from Nick and Kimberly.

I sent a message via Yelp on a Sunday night and they immediately scheduled our oven troubleshooting for Monday afternoon. Their front office staff is incredibly responsive! George (technician) arrived timely and was very thorough. He explained things to me every step of the way. He is approaching this very methodically - ok, so it's not the igniter, let's look at the next link in the chain... I saw George called out by name in other Yelp reviews, and I understand why he comes so highly recommended! He called the manufacturer to discuss his findings, but the manufacturer tech team wasn't available. He let me know he would be calling them again in the morning and that he would reach out to me with an update. I've had plenty of negative or so-so experiences with other service technicians from other companies. This experience with George / Astera is so positive that I'm posting my review even before the service is completed. Astera will be getting first crack at all of my appliance and HVAC service calls going forward.

When the AC stopped working on a Saturday when the temps were in the 90s, I decided to call Wally's hoping they would be able to send someone out on Monday. To my pleasant surprise, Rick Novak was at my house in less than an hour. In addition to being able to quickly diagnose and fix the issue with the AC, he was a genuinely friendly guy that was a pleasure to deal with. He had the AC working in no time, and reassured us that the unit was in overall good shape and wasn't in danger of needing replaced in the near future. Thanks, Rick!!

In the winter, the plumber cut a pipe to my HVAC unit without knowledge that he had cut off service to this unit. I didn't give permission for this to occur either. As a result, when I realized this is what happened, I called and asked them to fix the pipe as a pro bono measure since it was a mistake. I didn't feel it was my responsibility to pay for an error they made. Although it is December and cold out, it took them two phone calls and over four hours later to call me and let me know they would charge me for the work but they'd be happy to send someone out to do it. As a small business owner, I feel this is a terrible way to treat clients. It is important for businesses to take responsibility for the actions they have caused. I clearly told the owner on the phone that I would no longer be using their services moving forward.
